Product Overview
The B921C keypad is an SDI2 bus compatible device. The keypad features capacitive touch keys, instead of the mechanical buttons found on most keypads. With a smooth, sleek surface, the keypad is easy to clean, and fits with any modern decor. The keypad has user adjustable options such as volume and brightness. The keypad has three programmable emergency keys, and four inputs. The keypad also shows two-line system messages for all areas. The keypad uses words, numbers, and symbols to show the status of the security system. When several events occur, the keypad shows each event in order of priority. Each keypad has 10 number keys, 7 function keys, and 6 navigation keys. When pressed, keys turn on keypad backlighting and emit the keypress tone (short beep). The function keys include programmable function keys and keys to initiate arming and bypassing with one keypress. The keypad has a built-in speaker that produces several distinct warning tones. The tones are differentiated so that the user can recognize an event simply by hearing its associated tone. The keypad backlight illuminates when it emits an audible tone. Users can use a passcode to silence the tone.
